Abstract
An economic stackable container of foldable corrugated material with improved strength for forming a stable stack of containers. Ventilation spaces are provided between stacked containers. The arrangement of panel is disclosed. An extension formed at the top at each corner projects into a notch formed at the bottom of a respective corner of the container above. The panels are particularly reinforced by folded panels at the corners. A separate reinforcing sheet is applied around the periphery of the panels of the main sheet. The sheets have their corrugations in the various panels oriented for strength.
Claims26
A stackable container formed of foldable corrugated material, comprising:
- a bottom panel forming a bottom of said stackable container;
- a first end panel for forming a first end of said stackable container, said end panel being connected to said bottom panel by a fold line, said end panel having vertical corrugations;
- a first support panel for supporting an upper container on said stackable container, said support panel being connected to said end panel by a fold line, said support panel having vertical corrugations;
- a first side panel for forming a first side of said stackable container, said side panel being connected to said bottom panel by a fold line, said side panel having horizontal corrugations;
- and a first reinforcing flap for reinforcing said end panel, said reinforcing flap being connected to said side panel by a fold line, said reinforcing flap being connected to said end panel along a substantial portion of said end panel, said reinforcing flap having horizontal corrugations;
- an extension above said support panel for positioning an upper one of said containers on said stackable container;
- and
- an opening defined in at least one of said panels and located beneath said extension for receiving an extension of a lower one of said containers to position said stackable container on the lower container.
